Subject: the long-awaited video_out changes, not completely debuged (races) -
 pts are 64 bit now - scr and video_out-loop run all the time - video_out
 cleanups - metronom cleanups - buffer type BUF_CONTROL_DISCONTINUITY is used
 internally now,   input plugins should no longer send this one - support for
 individual frame durations - using nano-/usleep instead of itimer (simpler
 code, maybe this will   help freebsd)
